Abstract

An information notification apparatus includes a first reception unit that receives a first state change notification indicating that the operating state of an electrical appliance has changed to a first state, a transmission unit that transmits a state notification indicating that the operating state of the electrical appliance is the first state to an information terminal, and a second reception unit that receives an acknowledgement notification. The first reception unit further receives a second state change notification indicating that the electrical appliance has been changed to a second state from the electrical apparatus. The transmission unit calculates a correlation value for each of information terminals and transmits the state notification to an information terminal having a calculated correlation value higher than a threshold value, the correlation value indicating a degree of likelihood that the owner of the information terminal has performed an operation corresponding to the second operating state.

First claim

The invention claimed is:

1. An information notification apparatus for notifying at least one of a plurality of information terminals of operation information about an electrical appliance, the information notification apparatus comprising:
a storage unit;
a non-transitory memory device that stores a program; and
a hardware processor that executes the program and causes the information notification apparatus to:
receive a first state change notification from the electrical appliance, the first state change notification indicating that an operating state of the electrical appliance has changed to a first state;
in response to having received the first state change notification, transmit a state notification to at least one of the information terminals, the state notification indicating that the operating state of the electrical appliance is the first state; and
receive an acknowledgement notification indicating that the state notification has been acknowledged from the at least one of the information terminals to which the state notification has been transmitted, and store the received acknowledgement notification into the storage unit,
wherein a second state change notification is received from the electrical appliance and the received second state change notification is stored into the storage unit, the second state change notification indicating that the operating state of the electrical appliance has changed to a second state through an operation performed on the electrical appliance after the transmission of the state notification, and
a correlation value is calculated for each of the information terminals based on the acknowledgement notification and the second state change notification that are previously stored in the storage unit, and the state notification is transmitted to an information terminal among the information terminals which has a calculated correlation value higher than a threshold value related to whether an owner has changed the operating state of the electrical appliance to the second state, the correlation value being an indicator of whether an owner of the information terminal has performed an operation to change the operating state of the electrical appliance to the second state.

2. The information notification apparatus according to claim 1 ,
wherein the acknowledgement notification includes a state notification acknowledgement time that indicates a time of acknowledgement of the corresponding state notification,
the second state change notification includes a state change time that indicates a time of change in the state of the electrical appliance into the second state, and
a higher correlation value is calculated as a difference between the state notification acknowledgement time and the state change time decreases.

3. The information notification apparatus according to claim 2 ,
wherein positional information is received from each of the information terminals, the positional information indicating a position of the information terminal at the state change time, and
a higher correlation value is calculated as a distance between the information terminal and the electrical appliance at the state change time decreases.

4. The information notification apparatus according to claim 1 ,
wherein the state notification is transmitted to an information terminal that has a highest correlation value among the information terminals, and
when the acknowledgement notification is not received after an elapse of a predetermined period of time since the transmission of the state notification, transmit the state notification is transmitted to an information terminal that has a second highest correlation value among the information terminals.

5. The information notification apparatus according to claim 1 ,
wherein in response to having received the second state change notification, an operation complete notification is transmitted to the at least one of the information terminals to which the state notification has been transmitted, the operation complete notification indicating that an operation corresponding to the state notification has been performed on the electrical appliance.

6. The information notification apparatus according to claim 5 ,
wherein the operation complete notification is transmitted to, among the at least one of the information terminals to which the state notification has been transmitted, only an information terminal from which the acknowledgement notification has been received at a time at which the second state change notification is received.

7. The information notification apparatus according to claim 1 ,
wherein the state notification is deleted from, among the at least one of the information terminals to which the state notification has been transmitted, an information terminal from which the acknowledgement notification has not been received at a time at which the second state change notification is received.

8. An information notification system comprising an electrical appliance, a plurality of information terminals, and an information notification apparatus for notifying at least one of the information terminals of operation information about the electrical appliance,
the information notification apparatus including:
a storage unit;
a non-transitory memory device that stores a program; and
a hardware processor that executes the program and causes the information notification apparatus to:
receive a first state change notification from the electrical appliance, the first state change notification indicating that an operating state of the electrical appliance has changed to a first state;
in response to having received the first state change notification, transmit a state notification to at least one of the information terminals, the state notification indicating that the operating state of the electrical appliance is the first state; and
receive an acknowledgement notification indicating that the state notification has been acknowledged from the at least one of the information terminals to which the state notification has been transmitted, and store the received acknowledgement notification into the storage unit,
wherein a second state change notification is received from the electrical appliance and the received second state change notification is stored into the storage unit, the second state change notification indicating that the operating state of the electrical appliance has changed to a second state through an operation performed on the electrical appliance after the transmission of the state notification, and
a correlation value is calculated for each of the information terminals based on the acknowledgement notification and the second state change notification that are previously stored in the storage unit, and the state notification is transmitted to an information terminal among the information terminals which has a calculated correlation value higher than a threshold value related to whether an owner of which has changed the operating state of the electrical appliance to the second state, the correlation value being an indicator of whether an owner of the information terminal has performed an operation to change the operating state of the electrical appliance to the second state.

9. An information notification method in which an information notification apparatus including a storage unit notifies at least one of a plurality of information terminals of operation information about an electrical appliance, the information notification method comprising:
receiving a first state change notification from the electrical appliance, the first state change notification indicating that an operating state of the electrical appliance has changed to a first state;
